Our international collaboration is devoted to the observation and analysis of young eclipsing binary and multiple systems in various OB associations. Preliminary results reveal several higher-multiplicity systems. Modern analysis techniques such as spectral disentangling and comprehensive atmosphere modeling enable us to derive the atmospheric properties of the distant companions as well as the astrophysical parameters of the eclipsing binary components with high accuracy.
